I was hoping Zen3 was going to give me a compelling reason to upgrade my 7700K, but unfortunately not at these prices. The 10700k is £80 cheaper than the 3800x, and the 10 core 10850K is only £11 more. Unless there is a ton of overclocking headroom on Zen3, there probably won't be much between them once overclocked. We'll have to wait for reviews to find out. I'm more inclined to wait a few months until rocket lake and see where everything compares then. Hopefully PSU and RAM availability will be better by then too.
same here was hoping for bang for buck 8 core but probably just hold out now , still fine with my 6700k
